Factory Setting; Factory Setting - Single-Phase Tped Pumps; Setting By Means Of Control Panel; Setpoint Setting - Grundfos LME Series Installation And Operating Instructions Manual

The selector switches enable changeover between the operating
modes "alternating operation" (left position) and "standby oper-
ation" (right position).
The switches in the two terminal boxes must be set to the same
position. If the switches are positioned differently, "standby oper-
ation" is selected.
Twin-head pumps can be set and operated in the same way as
single-head pumps. The duty pump uses its setpoint setting,
whether it is made by means of the control panel, via the R100 or
via bus.
Note: Both pumps should be set to the same setpoint and control
mode. Different settings will result in different operation when
changing between the two pumps.
If the electricity supply to the pump is disconnected, the pump
setting will be stored.
The remote control R100 offers additional possibilities of setting
and status displays, see section 5. Setting by means of R100.

3.3 Factory setting

Note: For single-phase TPED pumps, see section 3.4 Factory
setting – single-phase TPED pumps.
The pumps have been factory-set to uncontrolled operation. The
setpoint value corresponds to 100% of the maximum pump per-
formance (see data sheet for the pump).
Other pump settings are marked with bold-faced type under each
individual display in sections 5.1 Menu OPERATION and
5.3 Menu INSTALLATION.
3.4 Factory setting – single-phase TPED pumps
The pumps have been factory-set to uncontrolled operation and
the additional operating mode "alternating operation".
The setpoint value corresponds to 100% of the maximum pump
performance (see data sheet for the pump).
Other pump settings are marked with bold-faced type under each
individual display in sections 5.1 Menu OPERATION and
5.3 Menu INSTALLATION.

4. Setting by means of control panel

At high system temperatures, the pump may be so
hot that only the buttons should be touched to avoid
burns.
The pump control panel, fig. 20, incorporates the following:
• Buttons, "+" and "–", for setpoint setting.
• Light fields, yellow, for indication of setpoint.
• Indicator lights, green (operation) and red (fault).

4.1 Setpoint setting

The desired setpoint is set by pressing the button "+" or "–".
The light fields on the control panel will indicate the setpoint set.
See the following examples, figs. 21 and 22.
Example: Pump in controlled-operation mode (differential pres-
sure control):
Figure 21 shows that the light fields 5 and 6 are activated, indicat-
ing a desired setpoint of 4 m with a sensor measuring range from
0 to 8 m. The setting range is equal to the sensor measuring
range (see sensor nameplate).
